Answer: A. Both fathers are violent and negative, while the sons are weaker and powerless.
Many critics believe that the overbearing father of Kafka is represented in his work, particularly in The Metamorphosis and Letter to the Father. Kafka had a troubled relationship with him due to his authoritarian and demanding character. He could not connect with his son and Kafka was often lonely during his childhood. This is reflected in The Metamorphosis, as Gregor's father is also negative, authoritarian and violent, while Gregor feels unable to stand up to him.
